From what I understand about having MPD/D.I.D. is that schizoaffective disorder is a fine line between the two.
yet they are so opposite.
I was diagnosed schizoaffective disorder then was diagnosed MPD at the time.
It turned out I was MPD by professional doctors that did tests on me etc...
There is no part schizophrenia and part MPD/DID. At least that is what I was taught by the 5 treatment facilities and therapists I have seen and a doctor I see now.
So my answer is NO....
However I don't know you so I can't say nor am I a doctor or your therapist.

to you though.
Does the meds help the voices?
